Abstract

The embodiments of the present invention provide an interference cancellation device and method, relating to the technical field of communications; the invention can prevent ADC/DAC dynamic range limits and effectively cancel a type 2 self-interference component. Comprised are: a radio frequency (RF) reference signal is obtained; an RF reception signal is received by means of a primary receiving antenna; according to the RF reference signal, type 1 self-interference component cancellation is performed on the RF reception signal, and a first processing signal is generated; according to self-interference channel parameters and the RF reference signal, the self-interference reconstruction signal is obtained; according to the self-interference reconstruction signal, a second self-interference signal in the first self-interference signal is canceled, generating a second processing signal; the second processing signal is downconverted, generating a third processing signal; digital/analog conversion is performed on the third processing signal to generate a digital signal; a digital baseband reference signal is obtained, and according to the digital baseband reference signal and the digital signal, self-interference channel estimation is performed to obtain self-interference channel parameters. The present invention is used for interference cancellation.
